humidity
Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.
Humidity is the measurement of the amount of water vapour in the air.
It is humidity.

Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
Relative humidity is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
the humidity condences and you get pure water. the air can only hold a certain amount of water vapour, that amount rises with temp so when you cool the air you can have excess water vapour which will condence to liquid water.
It means the relative humidity is high. (amount of water vapour in the air is quite close to the maximum amount of water vapour that the air can hold)
Water turn into a gas called water vapour. The air depending on its temperature will hold a certain amount of this. when the air comes into contact with water if the humidity of the air is such that it can hold more water vapour then the water that is touching the air will turn into the gas water vapour and become part of the air. it will do this at any temperature which explains why you can hang clothes out to drying sub zero temperatures and they dry.
